Beth Goodier is one of more than 100 young people in Britain diagnosed with Kleine-Levin syndrome, reports New Zealand Herald.

At the moment, Beth is two-and-a half months into another deep sleep episode. Nothing – not drugs, loud noises, pleading or cajoling – will wake her.

So her life is spent in pyjamas in bed or asleep on the sofa. On the rare occasions she leaves her home in Stockport, Cheshire, to see a doctor, she must be pushed in a wheelchair because she is too tired to walk.
